Holder/Flange is a critical mounting component for rupture discs, ensuring secure installation and pressure containment in industrial safety systems.

技术定义与适配语境
典型 夹持器/法兰 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

A Holder/Flange is a precision-engineered mechanical component designed to securely mount and seal a rupture disc within a pressure relief system. It consists of mating flanges that clamp the rupture disc in place, providing a leak-tight seal while allowing the disc to burst at its designated pressure rating. The component typically includes inlet and outlet flanges, gaskets, and bolting assemblies to maintain structural integrity under varying pressure and temperature conditions.

定义
A Holder/Flange is a precision-engineered mechanical component designed to securely mount and seal a rupture disc within a pressure relief system. It consists of mating flanges that clamp the rupture disc in place, providing a leak-tight seal while allowing the disc to burst at its designated pressure rating. The component typically includes inlet and outlet flanges, gaskets, and bolting assemblies to maintain structural integrity under varying pressure and temperature conditions.
工作原理
The Holder/Flange operates by creating a sealed assembly where the rupture disc is clamped between two flanges using bolts. This assembly maintains pressure integrity until the disc's burst pressure is exceeded, at which point the disc fractures to relieve pressure. The flanges distribute clamping forces evenly to prevent leakage and ensure the disc responds accurately to pressure changes.
材料
Common materials include carbon steel (ASTM A105)stainless steel (ASTM A182 F304/F316)alloy steelor nickel alloys for corrosive environments. Gaskets are typically graphitePTFEor spiral-wound metal.
